What is a CRE in sales?

Excuse me, could you please clarify what exactly a CRE stands for in the context of sales? I'm familiar with several acronyms, but I'm not sure which one applies here. Is it perhaps related to a certain position, role, or strategy within the sales industry? If so, could you elaborate on the responsibilities and key characteristics of a CRE in sales? I'm genuinely curious to learn more about this term and how it relates to the field.
